VARIATIONS  IN  MILK  AND  MILK  PRODUCTION. 

SUMMARY. 

The  yield  of  milk  from  different  cows  under  the  same  conditions 
differs  greatly,  and  that  from  the  same  cow  varies  widely  from  day  to 
day. 

The  composition  of  milk  is  highly  variable;  the  ratio  of  fat  to 
other  solids,  and  that  of  solids  to  water,  are  not  constant  as  between 
different  cows  or  for  the  same  cow  on  successive  days. 

The  percentage  of  fat,  or  of  other  solids,  is  not  always  highest  in 
the  smaller  yields,  but  cows  that  give  milk  with  a  high  per  cent,  of  solids 
generally  show  a  low  total  yield. 

Fat  is  the  most  variable  constituent  of  milk,  and  its  variations  are 
independent  of  those  of  the  other  solids;  therefore  the  yield  of  milk  is 
a  better  index  of  the  other  solids  than  it  is  of  the  fat. 

As  regards  the  first  and  last  milk  drawn,  the  proportion  of  solids  not 
fat  is  higher  in  the  first,  but  the  proportion  of  fat  is  decidedly  greater 
in  the  last. 

When  the  milking  periods  are  unequal  the  longer  period  will  gen- 
erally, though  not  always,  give  the  larger  yield  of  milk,  of  fat,  and  of 
solids  not  fat;  but  the  difference  in  yield  does  not  correspond  to  the 
difference  in  time;  that  is,  the  secretion  calculated  per  hour  is  greater 
during  the  shorter  period. 

Neither  day  time  nor  night  time  is  shown  to  be  superior  as  a  milk 
producing  period.

Different  cows  differ  in  their  power  to  make  milk  from  food,  and 
the  same  cow  varies  in  this  respect  from  time  to  time. 

It  pays  to  select  the  individual  according  to  her  power  to  manu- 
facture milk  from  food,  and  according  to  the  character  of  the  product. 

Aside  from  the  influence  of  food  or  environment  each  animal  ex- 
hibits individual  variations  of  her  own,  and  such  variations  tend  to  show 
something  like  periodicity  in  the  separate  functional  activities  of  the 
animal  body. 

How  THE  EXPERIMENT  WAS  CONDUCTED. 

For  a  period  of  ten  months,  beginning  May  i,  1897,  the  yield  of 
milk,  of  fat,  andiof  solids  not  fat  was  determined  for  each  of  five  cows 
and  separately  for  each  milking.  Of  the  cows  under  experiment  Dolly 
and  Janet  are  high  grade  Jerseys:  Jochemke  (called  Jock)  and  Lady 
Pietertje  Veeman  (called  Lady  Pietertje)  are  registered  Holstein- 
Friesians,  and  Eva  is  a  high  grade  of  the  same  breed. 

The  animals  were  pastured  during  the  summer,  and  in  fall  and 
winter  they  received  the  same  kinds  of  food  in  such  amounts  as  their 
appetites  required.  It  was  in  no  sense  a  feeding  experiment,  and  no 
attempt  was  made  to  compare  the  yield  of  milk  with  food  consumed. 
The  sole  object  was  to  study  the  daily  and  periodic  variations  in  the 
yield  and  the  character  of  the  milk  from  the  same  and  from  different 
animals  kept  under  conditions  as  nearly  as  possible  like  those  in  com- 
mon practice.  Throughout  the  experiment  the  milking  periods  were  by 
design  unequal,  the  period  from  morning  until  evening  being  1 1  hours 
and  from  evening  until  morning  13  hours.  This  inequality  is  common 
on  the  farm,  excepting  that  the  periods  are  generally  reversed  in  length 
during  the  summer  season. 

All  tests  were  made  in  duplicate.  Fat  was  determined  by  the  Bab- 
cock  method  with  accurately  calibrated  bottles.  The  solids  not  fat 
were  determined  with  the  Quevenne  lactometer  and  the  results  calcu- 
lated from  Babcock's  tables. 

To  discover  what  the  experiment  teaches  concerning  certain  general 
principles  the  records  of  all  the  cows  for  the  first  three  months  are 
compiled  and  the  results  tabulated  and  briefly  discussed.  The  records 
of  all  the  cows  for  the  month  of  May  though  voluminous  are  published 
in  full  to  facilitate  a  study  of  variations  as  between  individuals.  Fol- 
lowing this  are  given  full  records  of  one  of  the  cows  for  the  entire 
experiment  in  order  to  afford  data  for  a  study  in  individual  variations 
from  day  to  day  and  throughout  an  extended  period.  All  the  tables  are 
drawn  upon  for  data  bearing  upon  the  constitution  of  milks  produced 
under  varying  conditions  as  to  animals  and  time,  but  not  disturbed  by 
feed.  Last  are  certain  miscellaneous  data  of  interest  in  the  same  con- 
nection.

July  .... 

As  would  be  expected  the  largest  yield  is  at  the  morning  milking. 
The  only  exception  is  that  of  Jock  in  July  at  the  close  of  her  milking 
period.  Why  conditions  should  be  reversed  in  her  case  is  a  mystery 
that  is  not  cleared  up  by  the  closest  study  of  her  daily  performances. 
The  greatest  difference  in  favor  of  the  morning  milking  of  any  cow  and 
for  any  month  is  100.5  pounds,  or  18  per  cent.,  of  Lady  Pietertje  for  May. 

The  question  next  arising  is  whether  or  not  the  excess  of  the  morn- 
ing's milking  over  that  of  the  evening  corresponds  exactly  to  the  differ- 
ence in  the  length  of  periods  which  are  to  each  other  as  13  to  n.  To 
throw  light  upon  this  question  the  following  table  is  constructed:

Of  the  fifteen  calculations  in  the  above  table  ten  show  that  more 
milk  was  secreted  for  each  hour  of  the  time  from  morning  until  evening, 
and  five  show  more  milk  secreted  for  each  hour  of  the  longer  period 
from  evening  till  morning.  The  differences  in  favor  of  the  longer  period 
are  very  slight  and  never  over  .04  of  a  pound  per  hour,  or  about  4  per 
cent.  On  the  other  hand  the  excess  in  favor  of  the  shorter  period  is 
commonly  much  larger — in  case  of  Lady  Pietertje  for  July  rising  to  .12 
of  a  pound  or  n  per  cent.;  and  in  the  case  of  Eva  for  June  to  .  i  of  a 
pound  per  hour,  or  14  per  cent.  This  difference  in  favor  of  greater 
rapidity  of  milk  secretion  between  the  morning  and  evening  milkings 
may  be  due  either  to  the  shorter  period  or  to  the  time  of  day.  Experi- 
ments now  in  progress  in  which  the  milking  periods  are  each  12  hours 
in  length  have  thus  far  failed  to  show  any  advantage  of  the  day  over  the 
night  for  milk  secretions.  (See  table  TO,  p.  83.)  This  seems  to  indicate 
that  for  milking  periods  of  unequal  length  the  yield  of  the  shorter  is 
greater  in  proportion  to  the  time  involved  than  that  of  the  longer.

The  same  general  principle  appears  to  hold  in  the  yield  of  fat  as  in 
the  yield  of  milk;  namely,  that  the  greater  yield  is  from  the  longer  period. 
Yet  there  are  three  exceptions:  one  of  Jock  as  she  is  going  dry,  one  of 
Lady  Pietertje^  in  July  in  which  she  yielded  2^2  percent,  more  fat  in 
the  shorter  period,  and  one  of  Eva  in  the  same  month  with  a  slight 
excess  in  favor  of  the  evening  milking.  Again,  it  is  interesting  to  notice 
below  the  rate  at  which  this  fat  has  been  manufactured  per  hour  during 
both  the  longer  and  the  shorter  periods:

Even  more  pronounced  than  in  the  case  of  milk,  the  calculated 
hourly  manufacture  of  fat  is  greater  in  the  shorter  period.  Out  of  the 
fifteen  cases  there  are  but  three  exceptions.  In  two  of  these  the  secre- 
tion per  hour  is  the  same  for  the  two  periods  and  in  the  remaining 
instance  the  excess  in  favor  of  the  longer  period  is  but  .0001  of  a  pound 
per  hour,  a  difference  that  is  insignificant.  On  the  contrary  the  differ- 
ences in  favor  of  the  shorter  period"  are  pronounced  and  in  one  instance 
it  is  .007,  or  seven  times  as  great  as  the  greatest  difference  in  favor  of 
the  longer  period.  The  evidence  is  unmistakable,  and  to  the  effect 
that  the  rate  of  secretion  of  fat  is  more  rapid  for  the  shorter  period. 

Because  of  the  considerable  excess  in  time  in  favor  of  the  long 
period  more  fat  was  yielded  at  the  morning  milking,  and  yet  the  tendency 
to  greater  production  of  fat  during  the  shorter  time  was  so  marked  that 
in  nearly  every  case  the  average  per  cent,  of  fat  was  higher  for  the 
evening  milking.

With  one  exception  the  yield  of  solids  not  fat  is  greatest  for  the 
morning  milking,  and  that  exception  is  with  Jock  in  July,  whose  milk 
yield  for  that  month  is  higher  during  the  shorter  period.  This  excep- 
tion is  notable,  not  only  because  it  is  the  only  exception,  but  because 
the  excess  yielded  during  the  shorter  periods  amounted  .to  nearly  25 
per  cent.  It  will  be  noted  that  Jock  in  going  dry  reverses  nearly  every 
principle  established  by  the  other  cows.  That  this  is  due  to  individ- 
uality and  not  to  the  fact  of  going  dry  may  be  seen  by  a  study  pf  the 
records  of  Lady  Pietertje  for  October.  The  following  table  is  prepared 
in  order  to  learn  whether  this  excess  in  favor  of  the  morning  corresponds 
with  the  increased  time  involved:

Nine  of  the  above  instances  indicate  a  tendency  to  a  greater  hourly 
manufacture  of  solids  not  fat  during  the  shorter  period,  but  the  dif- 
ferences are  inconsiderable  and  notably  less  than  the  corresponding

differences  in  fat  production.  In  the  six  remaining  cases  the  rate  of 
manufacture  is  the  same  for  both  periods  or  slightly  in  excess  for  the 
longer.  This  substantially  agrees  with  the  yield  of  milk  as  a  whole 
rather  than  with  the  secretion  of  fat  which  tends  much  more  strongly  to 
be  higher  for  the  shorter  period.  So  true  is  this  that  the  following  table 
showing  the  average  per  cent,  of  solids  not  fat  for  the  morning  and 
evening  milking  exhibits  only  inconsiderable  differences,  which,  more- 
over, are  by  no  means  constant  as  between  morning  and  evening  milk.

With  four  exceptions  the  production  of  total  solids  calculated  per 
hour  was  higher  during  the  shorter  period.  Of  these  exceptions  three 
were  in  favor  of  the  longer  period  and  in  one  the  hourly  production  was 
equal  in  both  periods.  Notwithstanding  these  exceptions,  however,  the 
highest  average  for  each  cow  is  during  the  shorter  period.  The  study 
of  these  tables  seems  to  show  that  the  constitution  of  milk  varies  with 
the  length  of  the  milking  period,  unless  it  may  be  later  shown  that  the 
day  time  is  more  favorable  for  milk  production  than  is  the  night,  a 
contingency  that  has  not  yet  been  suggested  by  experiments  at  this 
Station,  as  shown  by  a  careful  study  of  the  following  table:

Rose  

The  above  is  taken  from  another  experiment  now  in  progress  and 
exhibits  several  remarkable  facts.  During  the  month  of  March  Eva 
gave  more  milk  in  the  evening  than  in  the  morning,  but  the  other  two 
gave  less.  In  April  the  yield  of  all  was  the  same  morning  and  evening. 
Lady  Pietertje  for  both  months  gave  more  fat  at  the  evening  milking, 
but  the  others  gave  less,  excepting  Rose  in  April,  leaving-  the  evidence 
divided.  Regarding  solids  not  fat,  they  all  gave  less  at  night  than  in 
the  morning,  excepting  Eva  in  March.  Differences  exhibited  in  this 
table  are  apparently  slight,  but  being  averages  should  be  significant. 
They  are  arranged  upon  opposite  sides  of  the  question,  and  yet  the 
differences  in  favor  of  the  morning  milking  are  greater  than  those  in 
favor  of  the  evening. 

The  following  complete  records  are  published  to  facilitate  a  more 
particular  study  of  variations  in  milk.  The  first  five  pages  are  for  five 
different  cows  during  the  month  of  May  to  afford  a  study  of  individual 
peculiarities.  The  fifth  and  nine  succeeding  pages  exhibit  the  record 
of  a  single  cow  for  ten  months  during  which  time  she  became  fresh. 

From  April  3oth  to  May  6th  all  the  cows  were  on  blue  grass  pasture, 
excepting  on  the  2d  when  they  were  confined  in  the  barn  all  day.  From 
May  7th  to  i5th  both  day  and  night  were  spent  in  pasture,  excepting  on 
the  pth  and  i3th  when  they  were  kept  in  the  yard  at  night  and  given  a 
feed  of  oat  hay.  On  the  evening  of  the  i5th  at  milking  time  the  floor 
of  the  barn  was  still  wet  and  slippery  from  scrubbing  and  considerable 
•excitement  was  developed  on  the  cows  coming  into  the  barn.  From 
May  1 6th  to  the  close  of  the  month  the  cows  were  continuously  on 
clover  pasture  instead  of  blue  grass.  On  the  evening  of  May  i3th  Jock, 
Lady  Pietertje,  and  Eva  were  milked  an  hour  later  than  common,  and 
on  the  morning  of  May  3oth  all  the  cows  were  milked  an  hour  earlier. 
Dolly  was  in  heat  May  igth,  and  Janet  May  26th.

DAILY  VARIATIONS  IN  MILK. 

The  mass  of  data  in  the  preceding  pages  precludes  anything  like  an 
-extended  discussion  within  the  limits  of  a  bulletin.  They  are  printed 
in  full  for  the  benefit  of  such  students  of  milk  production  as  may  be 
interested  in  giving  minute  attention  to  the  numerous  and  somewhat 
unaccountable  variations,  both  as  between  individuals  and  of  the  same 
animal  for  different  periods. 

It  is  only  in  the  most  general  terms  that  cows  may  be  said  to  rise 
and  fall  together  in  their  yield  of  milk.  The  tables  for  May  exhibit 
many  instances  in  which  for  a  time  the  individuals  by  twos  and  threes 
appear  to  be  influenced  by  some  circumstance  which  tends  to  increase 
or  decrease  their  yield  together  ;  but  shortly  one  of  the  animals  separates 
from  the  company  and  establishes  independent  variations.  The  sug- 
gestion of  these  experiments,  and  still  more  of  experiments  now  in 
progress,  is  that  individual  cows  are  subject  to  periodicities  of  their 
own,  either  because  of  the  different  influence  of  similar  environment, 
or  because  of  some  physiological  reason. 

The  reader  cannot  fail  to  observe  a  marvellous  variation  in  the  per 
•cent,  of  fat,  not  only  as  between  individuals,  but  with  the  same  individuals 
for  successive  milkings  and  days.  Jock  varies  from  3  per  cent,  to  4  per 
•cent,  in  the  morning,  and  from  2.7  per  cent,  to  4.2  percent,  in  the 
evening,  and  differences  nearly  as  great  may  be  noted  with  the  other 
^cows,  exhibiting  in  all  an  extreme  variation  within  the  month  and 
between  all  the  cows  from  2.7  to  5.7  per  cent.  It  is  by  no  means  true 
•that  the  highest  per  cent,  of  fat  is  found  in  the  smallest  milking,  because 
for  nearly  one-fourth  of  the  time  the  larger  percentage  of  fat  is  with  the 
;higher  yield  of  milk.  As  between  the  evening  milkings  of  Jock  May 
iiSth  and  ipth,  the  smaller  milking  is  found  to  be  deficient  in  fat  by 
fully  one  per  cent.  The  morning  milkings  of  the  i7th  and  i8th  are 
practically  identical  in  amount,  but  with  a  difference  of  .6  in  the  per 
cent,  of  fat.  That  these  differences  are  not  due  primarily  to  the  unequal 
milking  period  is  shown  by  the  extreme  difference  in  the  output  of  fat 
on  consecutive  days;  see  Jock  May  igih  and  20th  with  a  difference  of 
,34  of  a  pound,  or  40  per  cent.;  see  also  Lady  Pietertje  May  4th  and  5th 
with  a  difference  of  .22  of  a  pound,  or  nearly  25  per  cent.  Many 
similar  instances  can  be  readily  found. 

Extreme  variations  are  to  be  noted  in  the  matter  of  solids  not  fat. 
The  following  table  is  prepared  for  the  purpose  of  exhibiting  the  wide 
variation  in  the  percentages  of  fat  and  of  solids  not  fat  within  the 
month.

It  must  be  clearly  understood  that  there  is  no  relation  of  time 
between  the  maxima  and  the  minima  in  the  above  table,  that  is  to  say, 
the  maximum  percentage  of  fat  and  the  maximum  percentage  of  solids 
not  fat  may  be  upon  the  same  or  upon  different  days,  and  both  are  to  a 
great  extent  independent  of  the  yield  of  milk. 

The  last  column  but  one  of  the  milk  records  exhibits  the  ratio 
between  the  fat  and  the  solids  not  fat  for  each  day  of  the  experiment, 
and  here  again  notable  variations  are  discovered.  The  average  ratio  of 
fats  to  solids  not  fat  in  the  milk  of  Jock  and  Lady  Pietertje  for  May  is 
.37,  but  of  Dolly  for  the  same  period  it  is  .51.  The  extreme  variation 
noted  during  the  month  as  between  different  cows  and  at  different  milk- 
ings  is  .28  to  .61.  Nothing  could  be  more  positively  correct  than  the 
statement  that  milk  is  an  exceedingly  variable  product,  not  only  as 
regards  fat,  but  as  regards  the  proportion  of  fat  to  the  other  solids. 

The  fat  is  not  only  more  variable  than  the  solids  not  fat,  but  its 
variations  are  in  a  large  measure  independent  of  those  of  the  other 
solids.  There  are  therefore  some  notable  variations  in  the  column  of 
total  solids.  The  per  cent,  of  total  solids  is  by  no  means  highest  in 
the  smallest  yield,  as  for  Dolly,  May  3d,  when  both  fat  and  solids  not 
fat  are  abnormally  low.  The  consecutive  milkings  of  Lady  Pietertje  on 
May  roth  show  a  variation  in  the  per  cent,  of  total  solids  from  n.8  to 
13.2,  so  that  with  a  difference  of  2  pounds  of  milk  yield  practically  the 
same  amount  of  total  solids  were  secreted.  It  will  be  noted  in  passing 
that  about  this  time  Lady  Pietertje  was  giving  more  fat  in  the  smaller 
milkings  than  in  the  larger. 

BEHAVIOR  NEAR  THE  CLOSE  OF  A  PERIOD  OF  LACTATION. 

The  records  for  Jock  in  July  are  not  published,  but  close  study  of 
the  data  shows,  that  as  the  period  of  lactation  neared  the  close  the  daily 
yields  fluctuated  greatly  in  amount.  The  fat  was  unusually  variable, 
and  together  with  solids  not  fat  declined  in  proportion  toward  the  end. 


100 


BULLETIN    NO.   5  I. 


[May, 


The  ratio  of  fat  to  solids  not  fat  and  the  proportion  of  water  were 
unusually  high,  and  the  larger  quantity  was  given  during  the  shorter 
period. 

Lady  Pietertje's  record  is  published  in  full,  including  the  close  of 
one  lactation  and  the  beginning  of  another.  In  her  case  there  was  a 
slight  rise  in  the  percentage  of  fat  for  the  last  few  milkings  as  well  as  in 
the  per  cent,  of  total  solids,  both  conspiring  to  reduce  the  percentage 
of  water,  but  both  are  much  less  pronounced  than  in  the  case  of 
Jock.  It  will  be  noted  that  upon  beginning  to  milk  but  once  a  day, 
October  28th,  the  amount  of  fat  and  total  solids  immediately  dropped 
to  about  half  their  former  amounts,  showing  that  there  is  no  tendency 
to  compensate  for  the  milking  period  that  is  omitted. 

It  will  be  noted  also  that  at  the  beginning  of  the  new  lactation, 
November  i5th,  the  percentages  of  fat  and  of  total  solids  were  about 
normal. 

Ag  close  study  of  the  details  of  this  tabular  matter  cannot  fail  to 
impress  the  reader  with  the  belief  that  the  cow,  though  dependent  upon 
and  to  a  great  extent  influenced  by  her  environment,  is  yet  inclined  to 
indulge  in  many  and  often  extreme  individual  variations,  not  assignable 
to  any  visible  external  cause.  Experiments  now  in  progress  confirm 
this  view  of  the  case  and  tend  to  show  a  natural  periodicity  in  milk 
secretion,  such  periodicity  representing  something  like  the  algebraic 
sum  of  all  the  body  functions  whose  activities  rise  and  fall  to  some 
extent  independent  of  each  other  or  of  external  conditions.

1898.]  VARIATIONS    IN    MILK    AND    MILK    PRODUCTION.  IOI 

Eva  had  been  dry  for  38  days,  Tina  Clay  for  64  days,  and  Lady 
Pietertje  for  6  days.  The  first  milking  of  the  two  former  was  taken  12 
hours  after  dropping  a  calf,  and  that  of  Lady  Pietertje  at  36  hours. 

It  will  be  noted  that,  except  with  Tina  Clay,  the  quantity  of  milk 
rapidly  increased  within  the  week  to  more  than  three  times  that  of  the 
first  milking.  In  every  case  the  first  few  milkings  are  extremely  rich  in 
solids  not  fat,  but  the  percentage  at  first  is  widely  variable,  as  is  seen 
in  comparing  the  milk  of  Eva  with  that  of  the  other  two.  Eva  and 
Lady  Pietertje  begin  with  a  comparatively  high  per  cent,  of  fat,  but 
Tina  Clay  begins  low  and  increases  from  the  first.  It  will  also  be  noted 
that  this  fact  is  associated  with  larger  milk  yields  at  the  first  milkings, 
which  were  characteristic  of  Tina  Clay.  We  have  already  discovered 
that  the  daily  production  of  fat  is  nearer  corrstant  than  is  the  corre- 
sponding yield  of  milk,  and  this  low  per  cent,  of  fat  may  be  considered 
as  compensation  for  the  higher  yield  of  milk. 

COMPOSITION  OF  FIRST  AND  LAST  MILK  DRAWN. 

A  number  of  tests  were  made  of  the  same  and  of  different  cows  in 
order  to  discover  the  difference,  if  any,  between  the  first'  pint  of  milk 
drawn  from  the  udder  and  the  pint  last  drawn.  The  average  per  cent,  of 
fat  in  the  milk  of  each  cow  for  a  number  of  days  before  and  after  the 
trial  is  shown  in  the  table  for  the  sake  of  comparison.  The  udders  were 
washed  before  milking,  excepting  where  indicated  by  a  star.  It  was 
omitted  in  these  cases  under  the  impression  that  the  manipulation  inci- 
dent to  the  washing  might  affect  the  per  cent,  of  fat  in  the  first  milk 
drawn.  The  results  do  not  indicate,  however,  that  such  was  the  case. 
The  cows  were  milked  in  the  usual  manner,  through  a  funnel  into  a  pint 
bottle  until  the  first  pint  was  secured,  after  which  they  were  milked  into 
a  pail  until  nearly  finished.  Toward  the  close  they  were  again  milked 
into  bottles  confaining  one-fourth  of  a  pint  each,  and  when  the  milking 
was  finished,  the  last  four  quarter  pints  were  taken  as  representing  the 
last  pint  drawn. 

It  will  be  noticed  that  in  every  case  the  per  cent,  of  solids  not  fat 
is  higher  for  the  milk  first  drawn,  and  the  per  cent,  of  fat  lower;  but 
the  difference  between  the  fat  of  the  first  and  last  drawn  is  much 
greater  than  the  inverse  difference  between  the  solids  not  fat,  and  its 
fluctuations  are  wider  from  day  to  day,  and  between  different  cows.

COMPARISON  OF  Two  Cows. 


Two  mature  cows,  Eva,  a  high  grade  Holstein  weighing  1200 
pounds,  and  Janet,  a  high  grade  Jersey  weighing  875  pounds,  were  fresh 
on  the  same  day,  March  i6th.  They  were  immediately  put  under  experi- 
ment to  test  their  comparative  capacities  for  milk  and  butter  production. 
During  the  first  period  of  19  days  the  cows  received  equal  amounts  of 
bran  with  whatever  corn  stover  their  appetites  demanded.  During  the 
second  period  of  21  days  the  grain  ration  was  of  ground  oats  and  corn 
in  equal  parts  by  weight,  with  corn  stover  ad  libitum.  During  the  third 
period  of  28  days  the  grain  ration  was  unchanged,  but  the  roughness 
was  clover  hay,  and  during  the  fourth  period  of  23  days  the  grain  ration 
consisted  of  corn  meal  and  oil  meal  in  the  proportion  of  4:1  taken  with 
clover  hay  for  roughness.  Each  milking  was  weighed,  sampled,  and 
tested  separately. 

It  will  be  noticed  that  the  animals  always  received  the  same  amounts 
of  the  same  kind  of  grain,  and  were  allowed  to  satisfy  their  appetite  in 
roughness.  Though  it  cannot  be  said  that  the  refuse  from  this  rough- 
ness was  always  identical  in  feeding  value,  yet  the  animals  were  so  fed 
that  there  was  no  noticeable  difference  in  its  amount  or  character.  It 
will  also  be  noticed  that  roughness  was  corn  stover  the  first  and  second 
periods,  and  clover  hay  for  the  third  and  fourth,  but  that  the  grain  was 
the  same  for  the  second  and  third  periods,  so  that  there  was  never  a 
change  of  grain  and  roughness  at  the  same  time.  What  the  cows  did 
with  this  food  for  91  days  is  fairly  well  shown  in  the  following  table.

II.  O 

We  really  cannot  fail  to  note  that  Eva  gave  48  per  cent,  more  milk 
and  n  percent,  more  fat  on  the  same  amount  of  grain  and  with  an 
excess  of  roughness  amounting  to  only  112  pounds,  or  7.6  percent. 
This  points  to  two  principles,  namely,  that  some  cows  are  vastly  more 
economical  consumers  of  feed  than  are  others  and  that  the  character  of 
milk  produced  is  so  different  that  one  animal  may  excel  in  milk  and 
another  excel  in  fat.  These  cows  were  both  mature,  were  fresh  on  the 
same  day,  neither  suffered  accident  during  the  experiment,  yet  Eva  pro- 
duced 1057  pounds  of  milk  and  12  pounds  of  fat  out  of  an  extra  feed  of 
112  pounds  of  hay  and  corn  stover.  This  difference  in  favor  of  Eva  is 
far  greater  than  any  per  cent,  of  profit  the  dairyman  may  hope  to  make, 
and  it  teaches  that  in  the  last  analysis  profits  will  depend  upon  careful 
selection  of  the  animal  machine  that  is  to  transform  hay  and  grain  into 
milk  and  fat  and  money.
